In this learning activity you'll follow the process of converting digital data into a series of analog signals.

Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.

Learners read a description of the function of the coupling switch on an oscilloscope and how its setting affects measurements of DC, AC, and combined voltages. A brief quiz completes the activity.

Learners hear examples of customer focused responses to upset callers. They then practice rewording negatively phrased responses by employees.
